System requirements depend primarily on the number of IP flows that will be received and processed by the system. The bigger the network traffic volume, the higher the number of IP flows. This reflects strongly on IP flow processing speed and Raw Data file size. The former rises the CPU speed requirement and the latter rises the amount of HDD space needed to store Raw Data.

In addition to this, HDD space requirement rises with the number of Traffic Patterns and subnets you create and with the amount of Raw Data files you decide to store on your system. The number of Traffic Patterns you create also affects the IP flow processing speed.

The recommended server requirements assume default configuration for NetVizura NetFlow Analyzer. Significantly increasing the number of flows processed (above 10.000 fps on average), and monitoring nodes can increase CPU and memory requirements. Significantly increasing the number of flows and flow archive storing time will increase flow archive size and require more HDD space and/or additional external storage.

Assumptions: 10.000 fps, 1.000 counters, 30 days of Raw Data and 365 days of database history stored.

 

  • NetVizura comes with built-in database which will be installed on the NetVizura server. You can use a different server for your database to achieve better performance but note that NetVizura only supports PostgreSQL version 9.2 or higher.
  • NetFlow Analyzer Raw Data files are stored on the NetVizura server. You can store them in some other storage, but keep in mind that it can have a considerable impact on the performance due to large files being transferred across your network between the NetVizura server and Raw data files storage.

 

 

NetFlow Analyzer is highly flexible and you can configure it to minimize system requirements cost. To get more details on configuration, see NetFlow Settings > Configuration.
